if I a) don't want to sub-class GApplication and b) want to do local
command line parsing, it's pretty trivial to use a GOptionContext and
parse the command line prior to creating the GApplication. the only
difference between that and using local_command_line() is that with the
former you can create an Application instance with its initial state
already set up from the command line arguments parsing; and with the
latter you have access to an already existing Application instance that
you can change.

again: if you're pattern is to sub-class GApplication then
local_command_line() is probably a better choice; but we don't strictly
require sub-classing in gio and gtk+.

ciao,
 Emmanuele.
